Why does uterine prolapse occur?

Uterine prolapse is a common disease among women. There are many causes of uterine prolapse in women, the most common of which is childbirth injury. It can be said that uterine prolapse caused by childbirth reasons accounts for a relatively large cause of the disease. Of course, congenital developmental reasons are also relatively important. If it occurs, it must be treated in time to avoid continued harm to women's health. Let's take a look at this aspect.

Why does uterine prolapse occur?

1. Delivery injury

It is the main cause of uterine prolapse. Childbirth, especially difficult labor, prolonged second stage of labor or vaginal operative delivery, can easily cause damage to the cervix, cardinal cervical ligament, uterosacral ligament and pelvic floor muscles. If the supporting tissue fails to return to normal after childbirth, uterine prolapse is likely to occur.

2. Increased abdominal pressure

Most mothers in the postpartum period like to lie on their backs and are prone to chronic urinary retention. The uterus is prone to become posterior, with the axis of the uterus in the same direction as the axis of the vagina. When the abdominal pressure increases, the uterus will descend along the direction of the vagina and prolapse will occur. Chronic constipation and cough, ascites or abdominal obesity can increase abdominal pressure and cause uterine prolapse.

3. Congenital developmental abnormalities

Uterine prolapse in nulliparous women is caused by poor development of the supporting tissues of the reproductive organs.

4. Malnutrition

Severe nutritional deficiencies can lead to muscle atrophy, relaxation of the pelvic fascia, and loss of support for the uterus. Uterine prolapse caused by malnutrition is often accompanied by symptoms such as gastroptosis and abdominal wall relaxation.

5. Aging

Ovarian dysfunction leads to a decrease in estrogen secretion, which makes the pelvic floor support tissue weak and loose, making uterine prolapse more likely to occur or worsening the original prolapse.
